}

public class Test

Test t = new Test();

// Read a purchase order.

t.DeserializeObject("simple.xml");

}

private void DeserializeObject(string filename)

{

Console.WriteLine("Reading with XmlReader");

// Create an instance of the XmlSerializer specifying type and namespace.

XmlSerializer serializer = new

XmlSerializer(typeof(OrderedItem));

// A FileStream is needed to read the XML document.

FileStream fs = new FileStream(filename, FileMode.Open);

XmlReader reader = XmlReader.Create(fs);

// Declare an object variable of the type to be deserialized.

OrderedItem i;

// Use the Deserialize method to restore the object's state.

i = (OrderedItem)serializer.Deserialize(reader);

fs.Close();

// Write out the properties of the object.

Console.Write(

i.ItemName + "\t" +

i.Description + "\t" +

i.UnitPrice + "\t" +

i.Quantity + "\t" +

i.LineTotal);

}
